Abstract

The goal of the current experiment was to investigate the effects of explicit knowledge of reoccurring segments within the pursuit tracking task. We hypothesized this explicit knowledge to increase the predictability of the reoccurring segments, leading to a segment-specific performance improvement. However, we expected explicit knowledge to have an adverse effect when the task was combined with a working memory-loading cognitive task. In a two-day experiment, 20 young adults (Mean age = 24.0, SD = 3.6) were divided into two groups, an Implicit Group (IG) and an Explicit Group (EG). Within the trials of the pursuit tracking task, a reoccurring segment was hidden amidst randomized segments. The EG was made aware of the presence, location, and shape of the reoccurring segment, the IG was not. After the initial performance of the task, a concurrent cognitive task was added. In order to investigate for effects of a consolidation period, participants returned on a second day. General performance over time increased significantly within both groups. No evidence of segment-specific improvement was found in either group. Addition of the cognitive task showed a significant deterioration in general performance, but showed no segment-specific effects, either. Performance on the second day showed general—though not segment-specific—improvement when compared to the first day. The negative effect of the concurrent task was found to be less severe during the second day. We suspect the lack of segment-specific changes found to be due to the full-vision nature of the current experiment. Future studies that investigate types of motor learning within a pursuit tracking task should make sure to minimize predictability by perception through visual control.
